LDAP_DEPRECATED in OPENLDAP_REL_ENG_2_2

Why are perfectly good functions like ldap_add() and
ldap_unbind() deprecated in favour of the _ext() functions?
I don't want to have to pass two extra NULL parameters all
over the place for controls I never use.
When you talked about LDAP_DEPRECATED some days ago, I
thought you meant ldap_perror(), ldap_bind() & a few others.
_That_ sounded good.
